AILING. CARL SAGAN, 60, mediagenic astronomer; from a rare bone-marrow disease; in Ithaca, New York. Sagan is taking a leave of absence from Cornell to seek treatment for the potentially cancerous condition...
...digitally savvy filmmakers who have already transformed cinema. Lanier embodies a whole new genre of music that uses computers to create and disseminate its own distinctive sounds. Another practitioner on the rise is Italian astrophysicist Fiorella Terenzi, 30, who has been described as a cross between Madonna and Carl Sagan. Terenzi has used audio telescopes to intercept radio waves from a galaxy 180 million light-years away, then fed them into a computer, applied a sound-synthesis program to convert her data into music and produced Music from the Galaxies. Result: part New Age, part Buck Rogers sound track, played...
...necessary to visit and colonize other planets? Why do we feel compelled to travel to distant worlds? Aside from humanity's innate curiosity, some say that in the future, there may be a need to vacate planet Earth.

...Sagan traces the history of space flight and looks ahead to the time when humans will fly from a dying or imperiled Earth to other worlds, "terraforming" them to make them livable and inhabiting them to preserve the species.

Perhaps even more important, spacecraft may one day prevent a global...
...Sagan's optimistic vision, however, rather than any foreboding of apocalypse, that shines through every chapter of this handsomely illustrated ^ book. Anticipating human exploration of Mars, for example, Sagan foresees a Jeep-like vehicle carrying astronauts on the lookout "for rocks from ages past, signs of ancient cataclysms, clues to climate change, strange chemistries, fossils or -- most exciting and most unlikely -- something alive. Their discoveries are televised back to Earth at the speed of light. Snuggled up in bed with the kids, you explore the ancient riverbeds of Mars...
